"Only the official representative of an organization, business, celebrity, or band is permitted to create a Facebook Page."The Facebook system does not allow you to create new pages for large brands. For example, creating the following Company page for Coca-Cola returns this message ...
However, as a small business you can create multiple Facebook pages using the same brand name.
Although it is not supposed to be possible, Facebook does allow multiple pages of the same name within a given category. The system also allows users to create a page with the same name in all categories. As malicious users register pages to rank higher for social media keywords, the potential to become a big PR nightmare increases.
There are more bugs in the Create a Page system, but this is the main issue I found with small businesses brand names. In my opinion, this is a disaster waiting to happen with Facebook.
